Software and configuration data are obtained in module, are solidificated in the space FLASH of this module.
Upgrading is divided into two parts in software set: operating in the software client of upgraded module and operates in the software liter of MMM
Grade server.
After system electrification, modules send the order of request software upgrading to MMM module after system power-up；MMM mould
After block receives the software upgrading request of module, the software upgrade information of module is obtained according to software upgrading allocation list, and its is soft
Part upgrade information is sent to the module of upgrading；Module after receiving software upgrade information by its with it is soft in local software information table
Part information compares, and inconsistent is then the software of required upgrading；Upgraded module is obtained from MMM by TFTP agreement and is risen
The software of grade, and be solidificated in the local space FLASH；The module of upgrading needs to update local after completing software upgrading
Information in software information table.
MMM module is needed according to software upgrading allocation list after receiving upgraded module and obtaining the request for upgrading software to required
The module of upgrading is confirmed whether to need to upgrade the software, and file is sent to upgrading by TFTP agreement after confirmation needs to upgrade
Module.
The centralization upgrading for completing software needs the support of software upgrading allocation list, local software information table, TFTP agreement.
Software upgrading allocation list: module id, dbase, software version, compiling date, the corresponding of store path are closed
System.The information of upgrade file needed for logging modle mark is corresponding, the information of upgrade file is obtained for upgraded module.
Local software information table: storage dbase, software version, compiling date corresponding relationship.It records and is solidificated in this
The information of software in the ground space FLASH obtains local software information for module and provides support.
TFTP agreement: upgraded module is supported to obtain file from MMM module.Application software and configuration are obtained for upgraded module
Data provide support.
The problem of this system reconstructing method effective application software dynamically load, improve the reliability of avionics system
And maintainability.
In order to realize that software centralization upgrades, the software and configuration data of all upgradings are stored in MMM.Modules foundation
The mark of this module obtains the software to be upgraded and configuration data from MMM module, and is solidificated in the space FLASH；
MMM module provides the service for obtaining software and configuration data then for modules.All module operation vxworks5.5 operations system
System, and can store a large amount of data equipped with FAT file system.
The centralization upgrading for completing software needs the support of software upgrading allocation list, local software information table, TFTP agreement.
Software upgrading allocation list: module id, dbase, software version, compiling date, the corresponding of store path are closed
System.The information of upgrade file needed for logging modle mark is corresponding, the information of upgrade file is obtained for upgraded module.ID representation module
Slot position position, there is different modules different ID, Softwarename to indicate the title of software, and Version indicates software
Version information, date indicate the software last date of formation, and Path indicates the path that software stores in MMM module.
Local software information table: dbase, software version, the corresponding relationship for compiling the date.Softwarename is indicated
The title of software, Version indicate that the version information of software, date indicate the software last date of formation.
TFTP agreement: upgraded module is supported to obtain file from MMM module.Application software and configuration are obtained for upgraded module
Data provide support.
As shown in Fig. 2, system operating scheme is as follows:
1. client sends software upgrading request
After system electrification, when being in system software upgrading mode, modules send asking for software upgrading to MMM module
It asks (comprising the module I D of itself).
2. upgrading the acquisition of software information
After MMM receives the upgrade request of upgraded module, software upgrading allocation list is searched according to module I D, is obtained from table
The information such as title, version, date and path of upgrading software required for module return to upgraded module.
3. judgement needs the software upgraded
The module of upgrading compares after obtaining upgrading software information with the software in local software information table, if it find that version
This or compiling date are inconsistent, need to upgrade the software, if it find that not having in local software information table present in upgrade information
Have, needs to upgrade the software.
4. obtaining the software of upgrading
The module of upgrading takes the software upgrading for needing the software path upgraded and the module I D of oneself to be sent to MMM module
Business device, MMM module confirm that the module needs to upgrade this according to the ID of software path and upgraded module in software upgrading allocation list
Its software is sent to the module of upgrading in confirmation by software by TFTP backward.
5. software upgrading
It after the module of upgrading obtains software or configuration data, is written into local FAT file system, completes software
Upgrading.
It is table used in this example below, wherein table 1 is software upgrading allocation list；Table 2 is local software information
Table.
